PROBLEM TO BE SOLVED: To provide a fire extinguishment facility which has high fire extinguishment performance, can handle a large scale fire, and can be manufactured at a low cost.SOLUTION: A fire protection water tank 1 usable as a fire extinguishment facility includes: a water tank body capable of storing water and having a columnar shape; a fire extinguishment hose 7 used while connected with the water tank body; an air bag device 10 pressurizing the water in the tank body for discharging the water from the hose 7; plural tires fitted on an outer periphery of the columnar water tank body; pull means used at a time of rolling the fire protection water tank in a laterally fallen state; and a storage chamber 43 for storing the pull means. An air bag 11 included in the air bag device 10 is inflated by receiving a gas pressure and pressurizes the water in the water tank body forcibly so as to press away the water. No direct contact of a compression gas for pressure with the water prevents the pressure gas from being dissolved or dispersed in the water in the water tank body, thereby the whole water in the water tank body can be reliably discharged by the gas pressure.SELECTED DRAWING: Figure 7 |
